java - Data received from Activity bundle is not being displayed on BarChart in Fragment -
i making app i'm making api call data through volley , set parcelable arraylist , send parcelable arraylist through bundle fragment contains barchart used mpchart library.
problem: data not populated in barchart. static data populating in graph not dynamic data (parcelable arraylist) parse so, i'm wondering if have somehow notify adapter or data set being changed. don't know i'm going wrong. appreciated have been stuck since yesterday.
i tried refresh data in viewpager fragment
